# 3D IFC interface

> Navigate IFC models, inspect elements and record review issues.

The IFC viewer lets you inspect a building model inside Ideatura. You can look around it, hide elements, check properties and cut a section. Start by opening your own IFC file; the screenshots use a sample building.

## 1. Navigate IFC

Open the IFC model beside the conversation. Use **Orbit** to look around the building, **Pan** to move across the view and the mouse wheel to move closer or further away. Return to **Select** to pick an element.

## 2. Project panel

The **Project** panel groups the open model’s views under **3D** and **2D**. Select a view to open it, use **New 3D view** or **New 2D view** to start another, or **Delete view** to remove one from the panel.

## 3. Find elements

Use **Structure** to browse by **Hierarchy**, **Types** or **Annotations**. Search for an element and select it in the tree or model. Turn on **Sync selection with Structure** if you want the tree to follow your selections in 3D.

![Structure panel with grouping, search and selection controls.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/structure.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=91eaa47e105f25cbb4b452d337c29b2b)

## 4. Model visibility

Use **Hide** and **Show** beside an entry to see past surrounding elements. Hiding leaves the element in the model. Use **Focus** to bring an object or group into view.

**Clear selection and view changes** clears the selection and shows hidden elements again. It keeps your current viewing angle.

## 5. Element details

Select an element and open **Details** to inspect its properties. Check its dimensions and information alongside its position in the building; use **Focus** to bring it into view.

## 6. Annotate objects

Select an object or group and open **Annotation** to add a note attached to the model. Save it, then find it under **Structure → Annotations**. For marks on a captured view, use [markup](https://beta.docs.ideatura.ai/alpha/overview/viewers.md#add-markup).

![Annotation controls for adding a note to selected model objects.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/annotation.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=71cb7aaf777bb18fb9ff3c2b367b1bf0)

## 7. Issues and BCF

**BCF** is a format for sharing model-review issues, such as a note about a doorway and the view showing it. Open **Issues** and choose **Add BCF** to open an issue file, or **New BCF** to start one. Associate the relevant IFC models, then open an issue to inspect its viewpoint. **Export BCF** downloads the issues for sharing.

![Issues panel with BCF controls for model review.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/bcf.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=2f9ca81d6892a513cb7bc462549f5516)

## 8. Place a section

Choose **Drawing**, then **Place plane**. Start with **Plan**, **Front** or **Side** and position the plane through the part of the building you want to show. Adjust the depth limit to control how far the view extends.

![Side section plane through the Leadenhall model and its drawing preview.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/section.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=2b5ebf536c33d76d5e498c7b114ce50a)

Use **Cut model** to see inside the building, **Full model** to check the plane against the whole model, or **Hide model** to inspect the drawing alone. **Show drawing / Hide drawing** controls the drawing on its plane; **Swap planes** exchanges the source and depth limit planes.

![Section display controls for viewing the model and drawing around the cut.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/section-display.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=340a6920bc36338b6af0ea3bd4295566)

In **Drawing settings**, **Line weight** changes the thickness of drawing lines. **Controls weight** changes the thickness of the plane-placement controls.

![Drawing settings with separate Line weight and Controls weight options.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/drawing-settings.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=131d537fa6de6757a691f3c379a6bf60)

## 9. Review the drawing

Check **Preview**, then switch to **2D** to inspect the drawing. Switch back to **3D** to adjust the cut. If Studio reports an incomplete drawing, check which parts are missing before using it.

![Extracted 2D section with view controls and the section listed in Project.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/drawing.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=5324b1f0e3eb511ca7452f3bb41b9f65)

Use zoom and fit controls to inspect a detail, then add marks with the 2D toolbar and **Markup settings**. Choose **Attach** to add the marked view to a request: “Explain the stair arrangement in this section.”

## 10. Keep the drawing

Choose **Add to Project** to keep the temporary view in the current Project panel. **Close view** returns to the model. This view has no separate drawing download: **Clone** and the top download menu act on the model file.

![Temporary section view listed in Project with view controls.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/keep-drawing.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=6a4fbe15f302a3156e3fff436c95ac65)

## 11. Save the scene

Use **Save to Workbench** to keep an editable copy of the scene. Choose its name and folder, then **Save**.

![Save dialog for naming an editable scene copy and choosing its Workbench folder.](https://mintcdn.com/ideatura-preview/C0RIqgvjHXWRrPYD/alpha/images/ifc/save-scene.svg?fit=max\&auto=format\&n=C0RIqgvjHXWRrPYD\&q=85\&s=e5cad1843660f9077adf0948cd6b300b)

Open **Download and export** for **Download scene file** (saved scenes), **Export scene as GLB**, **Export scene as glTF** or **Download source IFC**. To download a source IFC from a scene with several models, select the model first. Source IFC download is unavailable if that model has been moved, rotated or scaled within the scene.
